Answer:
r = 6
Step-by-step explanation:
The equation is 3r + 18=6 + 5r. First, you have to get the coefficient on one side because it will be easier to solve. In order to do so, I subtract 3r from both sides. The equation is now 18=6 + 2r. The next step is to get the constant which is 6 to the left side. You subtract 6 from both sides. You are left with 12=2r. All you have to do now is to get r alone. In order to do that you have to divide both sides by 2. The answer would be 6. Hope you find this helpful!
